COPYING  RESTRICTIONS 

Reel  duplication  of  the  whole  or  of 
any  part  of  this  film  is  prohibited.

A  Note  on  the  Sources 

The  pages  which  were  microfilmed  for  this  collection  are 
in  generally  good  condition  in  the  original.  There  are 
some  pages,  however,  which  due  to  age  are  lighter  than 
normal.  Additionally,  because  some  volumes  are  very 
large  and  have  been  bound  tightly  and  cannot  be  un¬ 
bound,  there  are  intermittent  occurrences  of  slight  dis¬ 
tortion  of  the  edges  of  a  small  percentage  of  the  pages. 
We  have  made  every  technical  effort  to  ensure  complete 
legibility  of  each  and  every  page.

Mr.  Bissntowi,  M.E..& tlio  following 
results  its  obtained  in  his  examinations  of  the  several  motors 
in  regard  to  their  relative  cost  per  horse-power  for  oaeh  hour. 

It  will  be  observed  that  the  examination  pertained  principally 
to  small  motors.  The  relative  cost  per  effective  horse-poivcr 
per  hour  is  as  follows : — 100  h..p.  steam  engine,  7*0  \  2  h.«p.

A  Note  on  the  Sources 

The  pages  which  were  microfilmed  for  this  collection  are 
in  generally  good  condition  in  the  original.  There  are 
some  pages,  however,  which  due  to  age  are  lighter  than 
normal.  Additionally,  because  some  volumes  are  very 
large  and  have  been  bound  tightly  and  cannot  be  un¬ 
bound,  there  are  intermittent  occurrences  of  slight  dis¬ 
tortion  of  the  edges  of  a  small  percentage  of  the  pages 
We  have  made  every  technical  effort  to  ensure  complete 
legibility  of  each  and  every  page.
